Emeralds have a rich history and are one of the most loved precious gemstones worldwide. They are more than 20 times rarer than Diamonds and so can often command a higher price. They represent royalty, wit, eloquence and foresight with its green colour representing new beginnings, whether that be in love or life. They are also thought to improve concentration and memory. Emeralds have long been associated with glamour and style and were favourites of stars such as Elizabeth Taylor and Jackie Kennedy and even as far back as Cleopatra who was known to love them.
